Welcome to the TriLUG home page. We are a LUG dedicated to the Triangle area including Durham, Raleigh, Chapel Hill, and Research Triangle Park. This site, along with our wiki, will enable you to keep abreast of TriLUG information (meetings, events, news), and to communicate with local Linux and FOSS (Free and Open Source) enthusiasts.

The primary modes of interacting with us: mailing list, IRC, or coming to the monthly meetings.

Announcing the inaugural TriLUG survey!

Exciting times are at hand!

As one might guess from the subject of this announcement, the TriLUG Steering Committee is unleashing its first experiment in the realm of data and demographics. We have carefully crafted our inaugural online survey, one which we hope will reveal who our constituents are and how they feel about TriLUG.

Since we believe in open source and value your privacy, and thanks to the excellent LimeSurvey project, our survey is entirely hosted on TriLUG hardware. Your responses are anonymous and will not be shared with third parties. That said, please refrain from abusing your anonymity to the detriment of our efforts.

This is not an excessively long survey. However, you may want to set aside 15-20 minutes just to be safe. If you get interrupted, there is a button to save and resume later at the bottom of each question.

Though it should go without saying, survey participation is entirely voluntary. We don't know who you are, so no one will hold it against you if you roll your eyes and delete this message. But if you are willing to help TriLUG become the best LUG ever, follow the link below to begin...

 Take the TriLUG 2011 Official Survey

This survey will be active for approximately 30 days, so don't miss your chance to be heard. Shortly after it closes, we hope to publish a summary of the responses for all to see.

Any questions or concerns should be sent to the Steering Committee. Thank you in advance for your participation!

April 14 meeting: intro to iSCSI and cost effective NAS

Topic: A practical introduction to iSCSI and cost effective NAS solutions
Presenter: Jon Magrini
When: 7PM, Thursday April 14, 2011
Where: Red Hat Worldwide Headquarters
Permalink: http://trilug.org/2011-04-14/storage

Bio: Jon Magrini is a Red Hat TSE in the Storage SBR at Red Hat and joined their team a little over a year ago. His specialty is clustering, with a focus on storage related technologies. Jon's Linux experience started in the early 2000 era when he worked for Borland software and developed pluggable modules, using a pure java open-api for software products such as JBuilder and Together Control Center. His interest for storage started with employment at Red Hat and the purchase of his own EMC CLARiiON, which started a waterfall effect.

March 10 meeting - High Availability, Low Dollar Load Balancing

Synposis: True high availability load balancing traditionally involves specialized, expensive hardware and software. However, you can build advanced, high availability configurations without a single point of failure using nothing but open source tools and commodity hardware. This talk will include a discussion of several tools, configurations, and advantages and disadvantages thereof. All tools involved are 100% free and open source. As a bonus topic, Simon will tell you how to use open source load balancing tools to IPv6-enable your IPv4-only infrastructure with minimal risk, time and hassle.

About the Speaker: Simon Karpen is the system architect / wearer of many hats for VoiceThread, which provides a very powerful rich media asynchronous collaboration platform. He has also worked for the Shodor Education Foundation in the past, and is a current NCSU MBA student (class of May, 2011). Simon is a member of the NC*SA Steering Committee.

February 10 meeting - Hacking with Backtrack and Metasploit

When we deploy Linux servers on the Internet, they are exposed to the entire world, and they may be vulnerable to attacks. How can we know that they are secure?

As part of the security team at SAS, Ryan Linn tests systems against vulnerabilities, and he recommends ways to mitigate the risks. The tools that he uses are open source, and very sophisticated.

Ryan will introduce us to Backtrack4, the LiveCD with hacking in mind. He will show us how to use the tools to scan a network for vulnerable machines, test a target machine against a list of known vulnerabilities, and how to take control over a machine. PWN3D.

The world-wide Internet - you will never find a more wretched hive of scum and villainy. Backtrack4 is a must-have tool for anyone planning to put a computer into that environment.

New SSL certificates for web & mail

It's that time of year again. We have regenerated our SSL certificates for our web and mail servers. Most people will notice this when their email client tries to connect to "mail.trilug.org" (which is the server name that you should use). It will warn that the certificate has changed. The new mail certificate fingerprints are:

SHA1 = 92:8A:60:97:6C:A9:37:C7:67:E4:A7:65:92:2E:06:65:64:CD:A0:5F
MD5 = DF:00:29:BB:0D:99:6F:BA:58:06:0A:86:9E:DD:9D:CB

Accept no imitations.
